  • First Layer Calibration (i3)

    First Layer Calibration (i3)

    The First Layer Calibration is used to calibrate the distance between the tip of the nozzle and the print surface. The aim is to adjust the nozzle height until the ...

  • Extrusion multiplier calibration

    Extrusion multiplier calibration

    This is an advanced calibration, recommended only to experienced users. The Extrusion Multiplier allows the fine-tuning of the extrusion flow rate - simply described as how much filament comes out of the nozzle. In ...

  • Bed Level Correction

    Bed Level Correction

    This calibration is for advanced users only! Together with the Mesh Bed Leveling, the Bed Level Correction is an important feature designed to allow users to compensate for even the slightest ...

  • Linear Advance

    Linear Advance

    This is an advanced calibration, recommended only to experienced users. Linear Advance (LA) is a technology that predicts the pressure build-up in the extruder when printing at higher speeds. The firmware of the ...

  • Live adjust Z

    Live adjust Z

    Every FFF (Fused Filament Fabrication) printer requires a First Layer Calibration, which sets the vertical "Z" distance between the nozzle and the print surface. Sometimes this value needs a slight ...

  • XYZ Calibration (MK3/MK3S/MK3S+)

    XYZ Calibration (MK3/MK3S/MK3S+)

    The XYZ calibration is a process, which checks, whether the printer was assembled correctly and the axes are perpendicular to each other. It measures the skew of your X/Y axis ...

  • Idler screw tension

    Idler screw tension

    The Original Prusa FFF printers and upgrades use a screw(s) with a spring(s) to provide tension between the filament and the filament pulley. It is important to have this tension ...

  • Squaring your MINI

    Squaring your MINI

    During transport, assembly, or maintenance (like adjusting the belt tension) the printer can become slightly skewed, where one axis may not be perpendicular (90-degree angle) to another. The firmware compensates ...

  • Mesh bed leveling

    Mesh bed leveling

    The P.I.N.D.A. or SuperPINDA sensor will go through a number of points, in a grid pattern, spread across the build-plate (whether it is a powder-coated or smooth PEI sheet does ...

  • Check Axis Length X/Y/Z (MK3S)

    Check Axis Length X/Y/Z (MK3S)

    This error can appear during the Self-test or the XYZ-calibration when the firmware detects a shorter distance of axis travel than expected. The exact length of each axis is stored ...
